The Naked Truth
As a cyclist you belong to the naked, unprotected group in the traffic. You don't have a metal shield or a safety belt to protect you. The most important thing you've got to protect is what you have inside your helmet.

I participated in the Pirkka Cycling (Pirkan pyöräily) in 2000. This was the first (and last?) time and I really enjoyed cycling the 134 km Fitness Tour. I started at 9.21 and finished 8h25min later. I had planned on ten hours, so I was quite pleased with the result.
